Read the 'Drowned World' by J.G. Ballard, humans start having ancient dreams.

'Just as psychoanalysis reconstructs the original traumatic situation in order to release the repressed material, so we are now being plunged back into the archaeopsychic past, uncovering the ancient taboos and drives that have been dormant for epochs… Each one of us is as old as the entire biological kingdom, and our bloodstreams are tributaries of the great sea of its total memory.
